| Abstract: | Leaf surface wetness duration and amount of dew are often two critical factors in the development and spread of plant diseases,especially of mycosis. Having analysed the advantage and disadvantage of all kinds of the instru- mets of leaf wetness measurement made by other countries,we designed and trial-produced electrical flat-plate impedance sensors and introduced its mate- rial,shape,size,colour surface treatment,and recorder. After test and using the instruments in the laboratories and corp fields,it has... |
